Rockbox 3.5 on V1 Fuze

Are there any downsides or problems with this  for the V1 Fuze? If I try it and don’t like it, are there any problems with uninstalling and going back to the sansa firmware? Is the rockbox truly gapless?

Yes its gapless and you can uninstall it (see manual for instructions).
